Toall 'whom t may concern:

Be it known that I, WILLIAM ADELBInT A TIFT, a citizen of the United States, resid# lation of waterethrough the water jackets of ing at Friday' Harbor, in the county of San Juan and- State of Washington, have 1nvented certain new and useful Improvements in Gas-Engines,- of which the following 1s a Specification, reference being hadtherein to the accompanying drawing.

This invention relates to-gasolene engines and has special reference to a 1nulti-cyli`Ii-- der engine 'wherein the cylinders revolve around a stationary crank shaft.

The principal object of theinvention is to provide an improved form of engine of this description having nove-l means for supplyingand exhausting the gases from a plurality of rotating cylinders.

Another object of the invention is to provide novel means for controlling the circu-v said cylinders..

Al third-object of the' invention is to provide a novel timer arrangement and connections therefor,-.fo`r us with such cylinders.-n 1

l.With the above and other objects in view, thisinvention xconsists in general of certain novel constructions, combinations and ar-y rangements of parts, as will be hereinafter fully described, illustrated "in the accompanying drawings, and specifically claimed. In the. accompanying drawings,- like characters of reference indicate like parts inthe severalviews, and Figure 1 is a vertical median. section through such an engine', the same being shown partly in elevation. Fig. 2 is a detail section pn the line 2'-2, of Fig.

certain of-the parts being broken away or shown in section. Fig. 4 is a section on the line 4 4, of Fig. 1, certain of the\-parts being omitted. Fig. 5 is an enlarged detail view showing the timer mechanism, .water pump, and adjacent parts. Fig. 6 is a detail section through a certain member containing exhaust and circulating water passages. Fi'g. ''.is a detail section showing one of the cams used toz operate thel timer.

Fig. 8 is an end view of the exterior of the timer casing. Fig. 9 is a detail view of certain contacts used in connection with the certain cam mechanism used to control the exhaust valves.

In the 'present embodiment of t-he invention there is provided a bed plate 1 from which standards 2 and 3 ext-end upward ing 9 by means of bolts 10 as' clearly shown in F ig. 3. y 5 Mounted in the casing 9 is a series of cylinders 11 each of Which is provided with a. pair of oppositely disposed trunnions 12 and 13 arranged to permit an oscillatory movement of the cylinders'with reference to the casing. Leading from each of the trunnions 12 is the l; 14 ofa pipe 15, this L being provided with a- Harigev through `which pass the bolts 16 which secure lthe pipe to the side frame 5. The other -end ofthe pipe 15 is threadedlinto the hub of the side frame 5 and communicates with anannular passage 17 extending around the Inner periphery of said hub. This passage 17 communicates with a passage 18 which extends outward through what may be termed the hub of the/member 4 and the outer end the passage 18 is threaded as at 19 for the reception of the pipe leading. from the car'- bureter.

Each of the trunnions 13 communicates with one end 20 of an S-shaped pipe. 21

which is secured to the casing 9 in the same anv manner that the pipe 14 is secured. The other end 22 of the pipe 21 is connected with one end -23 of an S-shaped pipe 24 by means of bolts 25 which pass through flanges 26 formed on the adjacent ends of the pipes 21 and 24, respectively. The remaining end 27 of'each pipe 24 is connected with a passage 28 by means of bolts 29 passing through anges 30, formed in'amember 30 which ,is lixed upon the shaft 7. This passage 28 communicates with an.' exhaust pipe '31. by

means of ana-nnular groove 32 formed on' the inner side of the casing 33 which is provided with suitable packing glands 34 and 35 and' is secured'to the standard 3 ixedly by means of the bolts 36.

Each of thecylinders 11 i's provided with ico the arms'54 and 55.

a piston 37, each of which is connected by a neck 37 to a segmento-cylindrica? bearing 38 which engages a crank 39 formed on the member 4. This crank is eccentric to the easing 9 and consequently if the latter be rof tated ythe pistons will be alternately forced in and drawn out. Conversely, if the pistons are forced in `and drawn out, they, with the keyed to the hub 44 of the side frame so that as the casing revolves so also will the shaft.

revolve.

, Within each of the trunnions 12 is mounted an intake vvalve 45 which is provided with a spring 46 and has its stem slidably mounted in a bearing 47 held in position by spaced brackets 48 secured to the inner walls of the trunnion. Tithin each of the trunnions 13 is an exhaust valve 49 similar to the valve 45 but provided with a ball and socket connection 50 which joins the stem of the valve proper with a stem 51 which projects outward from the pipe 21 and has mounted on its outer end a spring 52 and collar 52 to hold the valve in closed position.

Secured to each of the pipes 21 is a bracket 5 3 upon which is pivotally mounted the central part of a bell crank lever provided with The arm 54 bears against 'the end of the stem 52 while the arm 55 is provided with a suitable opening for the reception of the end of a rod 56, the arm being adjusted with respect to the rod by means of a nut 57 held upon the threaded portion of said rod. The lower end of the rod 56 is bifurcated and each of the bifurcations is again bifurcated to provide the fingers 58. These fingers 58 straddle a shaft 59 and between the first bifurcations is revolubly mounted a roller 60 and on the shaft 59 is a cam 61 which engages with the roller. The shaft 59 for each Vrod 56 is mounted in a bearing 62 formed on the side member 6. Mounted upon the shaft 59 is a gear 63 which meshes.' with a gear 64 actuated upon the member 43 so that the gear 64 jackets 67 of the respective cylinders there is provided within the casing an annular pipe 68 which communicates with` the respective jackets 67 through branch pipes 69 which are partially constructed of iexible material such as rubber hose. C onnected with this pipe 68 is a pipe .70 which communicates with an annular passage 71 formed in the member 30', this passage in turn communicating with a supply pipe 72 by means of an annular groove p13-formed in' the member 33. The pipe 72 communicates with a circulating'pump 74 held on a bracket 75 held to the standard 3 by the `same bolts 36 which hold the member 33 to said standard. This pump is provided with suitable inlet and outlet valves not deemed necessary here to be shown. Actuating the piston of the pump 74 is an eccentric 76 which is fixed Vupon a shaft 77 revolubly mountedin abearing 78 formed on the member 75. The overflow from -the water jackets of the cylinders is carried through pipes 79 whlch connect to one of the cylinders partially constructed of rubber hose, and each of these pipes 79 is connected to the waterjacket 80 of a respective pipe 21. From each of these water jackets 80 it-passes througha passage 81 and communicates with the respective pipe 24. y

In order to eHect the ignition of the gases I prefer to do so by means of the jump spark system. In carrying out this part of the invention there is provided a gear wheel 82 which is fixed upon the shaft 7 and meshes with a gear wheel 83 ixed upon the shaft- 77. There is also fixed upon the shaft 77 a gear wheel 84 which meshes with a gear wheel 85 provided with an elongated hub. On the hub of the gear wheel 85 is a series of cams 86, equal in number to the number of the cylinders 11 and inclosed by a. housing or casing 87 which is supported by an arm 88 provided with a bearing 89 journaled on the bearing 8 of the standard 3. Located in the plane of the path of the respective cams is a series of insulated binding posts 9G to which the 'wires forming the high tension -circuit are connected. Pivotally connected to the casing 87 are also a series of -levers 91 equal in number to the vnumber of cams and veach bearing upon a respective cam 86 being. pressed thereon by the springs 92. Each of the springs 92 carries at one end a contact point- 93 and these contact points are arranged to contact with the inner ends of the respective posts 90. V

Projecting from the arm 88 is an arm 94 which is-provided with spaced bearings in which is slidably mounted an insulated rod 96, the insulation being surrounded by metal tube v97 which is threaded for a portion'of its lengt-h. On the threaded portion of thel tube there is provided a nut 98 and between this nut and one of the bearings 95 is a spring 99 which norn ally urges the rod in the direction of the cylinders 11.

Extending through the arm 88 and the bearing 89 is a threaded set screw '100 which mangues is used' to mov-e the arm 88 around the shaft 7 and thus vary the position of the rod 96 whereby the' spark may be advanced or retarded.

Secured to the member 30 is a series of brackets 101, each provided on its outer end with a bearing wherethr'ough passes a bindtive' binding post 102 by suitable wiring not deemed necessary here to be shown as the same is obvious.

On the journal: member 4 is mounted a pair' of annular angleirons 105 which are pressed against the hub 5 by means of the springs 10c.

Attached to the casing 9 by meansof bolts 108 is a plate 107, the bolts passing through suitable ilanges 109. The plate thus forms a' portion of one of the flanges in the casing' 9 but at `the same time by its removal .permits the removal of the cylinders.

The operation of the engine is as follows: In order to start the engine the casing 9 is rotated by any suitabl'efnieans and j the pistons 37 are moved in and out ofl the -respective cylinders, the said suction `takrespective cylinders, as previously'l described. This causes a suction within the ing placesuccess'ively' in the series. Further rotation of t-he casing 9 causes compression of the drawn in gases and when the cam 86 for one of the cylinders is in proper position and the respective post 102 engages the post 94 a spark will Icross the spark gap' of the plug and an explosion will take place. This causes the rotation of the casing and cylinders therewith as previously described. The cylinders will thus be successively -r'e'd and upon further rotation will be on` the exhaust stroke. Now,'as the gear 63 is carrie'd around the fixed gear 64 and cam 61 will be operated for therespective cylinder` to which it belongs. Thereupon at the proper ltime the rod-56 will be raised andl theval-ve 4:9 opened, thus permit-ting the exhausted gases to pass out through the pipe 21 and its connections into the grooves .32. from whencelthey will pass backward into the cylinder itself .because it will be carried out with the exhausted gases during th`e exhaust stroke.

There has thus beenl provided a simple and eiiicient device of thel kind described, and for the purpose specified.y

It is obvious that many minor changes may be made in the form and construction of the invention without departing from the material principles thereof, and it isA therefore not wished to confine the invention? tov the exact form herein shown and described, but it is wished to include all such as prop-A erl'y come within the scopey claimed, Having'thus described the inventiomwliat isV claimed as new, is 1.- In a gas engine, afstandard,ga journai member xed in said standard, a crank projecting eccentrically from said journal member, a bearing at the opposite end of said crank, a casing revolubly mounted on said journal member,a second standard having a bearing in alinement with the first-mentioned bearing, a shaft carried in said'bea' ings and fixed lto said revoluble casing, a plurality ofA cylinders mounted for oscillatory movement in said casing, a water jacket for each cylinder, a pipe extending in a circle within said casing, a ie'x-ible congu nection between each water jacket and said pipe, exhaust pipes leading from said cylinders, and a exible connection between each exhaust pipe and the water jacket ofthe respective cylinder. 95
